Modified Hardcoded channel Number as 1 to dynamic.

While Getting user info using "Get User Info" keyword by default
it will return channel numebr 1 user. we have to mention the channel
number to get the particular channel user info. So for Get User Info
keyword added ${CHANNEL_NUMBER} variable as argument.

And also while getting channel access we are hardcoding the channel
number as 1, there are removed 1 and added ${CHANNEL_NUMBER}.

Tested: Run robot ipmi/test_ipmi_user.robot
        Run robot ipmi/test_ipmi_payload.robot
        Run robot redfish/account_service/test_ipmi_redfish_user.robot
